Jaguar's distinctiveness in a market dominated by German brands has always been one of its strongest selling points. After all, there's nothing on the road that looks like the 2015 Jaguar XJ, not the Mercedes-Benz S-Class, BMW 7 Series, Audi A8 or Lexus LS. That exclusivity continues inside, with an interior that equals its German and Japanese rivals in comfort, features and convenience, but without copying any of them. It used to be that Jaguar's style and luxury came with the bitter pill of poor reliability and quality. However, in recent years Jaguar has narrowed the gap with its rivals, even if it hasn't closed it completely. With short- and long-wheelbase models, and even a high-performance XJR model, this big Jag is a contender.
